Former Facebook CFO David Ebersman is now CEO of a startup. There’s a big difference

David Ebersman spent five years as chief financial officer at Facebook Inc., where he took the company public. Now, he’s taking a turn as chief executive of his own startup, Lyra Health, based in Burlingame, Calif.

Lyra provides companies and health plans with technology and other resources designed to improve the effectiveness of employees’ mental-health care. It has $3.1 million in strategic funding from Castlight Health Inc., a San Francisco provider of health-care management technology.
